Santos Place Brisbane, a six-Star Greenstar as built and five star NABERS rating.

20 September 2011 – A survey of green office buildings has shown they are almost twice as energy efficient compared to the average office building but individual control of temperature and ventilation needs attention

The study by Hikari Kato and Ann Murugan of the Institute of Sustainable Development and Architecture, Bond University in association with the Green Building Council of Australia surveyed 31 buildings in all states and territories except the NT (the NT didn’t match the criteria at the time of the survey)

The study found:

  • Green Star certified buildings are almost twice as
  • energy efficient as the average office building
  • 66 per cent of Green Star certified buildings are
  • performing better or on target for their expected energy
  • efficiency after 12 months of operation
  • Green Star certified buildings are significantly more
  • water efficient than average Australian offices
  • The commissioning process was very important to
  • owners in order to achieve ultimate building performance
  • Private car is still the most frequently used mode of
  • transportation among respondents
  • Many owners and tenants undertake a number of
  • sustainability measures and activities above and beyond what is
  • required by the Green Star rating system

Recommendations are:

  • A more interactive approach to education such as green building induction programs and workshops which seem to be more effective compared to the distribution of tenant guides.
  • Individual control of thermal comfort
  • Development of an effective green strategy
  • Use of sustainability experts

There was a general lack of understanding of green systems (42 per cent), and as only 37 per cent of staff surveyed knew how to adjust temperature  or ventilation thermal comfort  was the number one complaint.
